High-fracture-resistance concrete and preparation method thereof
The invention discloses high-fracture-resistance concrete and a preparation method thereof. The high-fracture-resistance concrete is prepared from the following raw materials in parts by weight: 110 to 130 parts of gravel, 100 to 150 parts of sand, 40 to 60 parts of cement, 10 to 20 parts of nano silicon dioxide, 20 to 30 parts of clay, 3 to 5 parts of water reducing agent, 4 to 8 parts of polypropylene fiber, 2 to 4 parts of carboxymethyl cellulose sodium and 100 to 150 parts of water. According to the concrete disclosed by the invention, by adding the clay, the polypropylene fiber, the nano silicon dioxide and the carboxymethyl cellulose sodium, the tight combination of all the raw material components can be improved, the hydration of the cement is remarkably promoted, and finally the compressive strength and the breaking strength of the prepared concrete are improved.
本发明公开了一种高抗折混凝土及其制备方法，该高抗折混凝土包括如下重量份的原料：碎石110～130份、沙子100～150份、水泥40～60份、纳米二氧化硅10～20份、黏土20～30份、减水剂3～5份、聚丙烯纤维4～8份、羟甲基纤维素钠2～4份和水100～150份；本发明混凝土中通过黏土、聚丙烯纤维、纳米二氧化硅、羟甲基纤维素钠的添加能够提高各原料组分紧密结合，并显著促进水泥水化，最终提高制备混凝土的抗压强度和抗折强度。
